February 08, 2021
Starting today, all existing and new out of office events will be updated to set the organizer to unknownorganizer@calendar.google.com
instead of the Calendar owner. It may take 2-3 weeks for this change to fully roll out.
You can use the calendarId from the API endpoint https://www.googleapis.com/calendar/v3/calendars/calendarId
to identify the owner of the out of office event.
February 01, 2021
The Calendar API now exposes a new field for events. The new field is called eventType
and allows users of the API to distinguish special event types, such as outOfOffice
. For more information, see the API reference.
January 11, 2021
From now, we require conferenceData
to be consistent with conferenceData.conferenceSolution.key.type
; meaning only Google Meet calls can have conferenceData.conferenceSolution.key.type
set to hangoutsMeet
. All 3P video conference providers are expected to set conferenceData.conferenceSolution.key.type
to addOn
.
September 07, 2020
Meet video conferences should be added explicitly using the following existing parameters:
- Set
conferenceDataVersion
query parameter to1
. - Set
conferenceData.createRequest
event property as follows:conferenceData.createRequest.conferenceSolutionKey.type
tohangoutsMeet
.conferenceData.createRequest.requestId
to unique request id.
We stopped auto-populating Meet for API calls (such as Events.insert
) to prevent Meet conferences being added unintentionally via 3rd parties.
March 16, 2020
Service accounts created on or after March 2, 2020 are only able to invite guests using domain-wide delegation of authority.
September 27, 2019
The Calendar API allows attaching a conference data of type addOn
to a new or existing event using Events.insert
or Events.update
methods.
November 19, 2018
Starting on January 7, 2019, notifications and reminders using the sms
method type will be ignored. The API calls setting such notifications and reminders will still succeed and modify all the other fields.
Since Calendar offers in-app notifications, you can still get notified, regardless of your device or connection. For more information see Google Calendar SMS notifications to be removed.
October 31, 2018
The Calendar API now supports four new OAuth scopes. The scopes allow your application to limit access to only the data you really need. See Authorizing Google Calendar API Requests for more details.
October 02, 2018
A more flexible approach to sending event change notifications is now available through the sendUpdates
parameter. The new parameter lets you set event change notifications to do one of the following:
- Notify all the event guests.
- Notify only the guests who are not using Google Calendar.
- Completely suppress the notifications, for example, during a migration.
Now it is possible to always keep in sync guests who use other calendaring systems, without sending too many non-mandatory emails to Google Calendar users.
March 22, 2018
Support for the JSON-RPC protocol and Global HTTP batch endpoints has been deprecated, and will be fully discontinued on March 25, 2019. This change is being made to the Google API infrastructure and as such affects multiple Google APIs, including Calendar v3.
For more information and migration instructions, see the Discontinuing support for JSON-RPC and Global HTTP Batch Endpoints blog post.
July 12, 2017
Hangouts and Google Meet conferences are now supported in Calendar events via the conferenceData
field. You can:
- Read conference data associated with events.
- Copy conference data from one event to another.
- Request new conference generation for an event.
- Clear conference data associated with events.
